Words: 258

Pages: 2

The major human effects of the phosphorus cycle include mining the phosphorus and distributing it on farmland. Nitrogen currently provides many benefits to society in particular to agriculture and industry. Humans have really influenced the phosphorus cycle by mining phosphorus changing it to fertilizer and products around the globe. Other major stores of nitrogen consist of organic matter in soil and the oceans. Despite its richness in the atmosphere, nitrogen is often the most limiting nutrient for plant growth. One major concern of human-driven changes in the nitrogen cycle has been local and worldwide change in the chemistry of the atmosphere specifically, increased emissions of nitrogen-based trace gases such as nitrous oxide, nitric oxide,

Essay on Human and Phosphorus Cycle

Nitrogen, Carbon, and Phosphrous Ecosystem Cycles Environmental Science-26 April 23rd, 2013 There is no denying that humans have an impact on the various cycles. However some of those impacts can be good, and unfortunately some of those impacts can severly hurt the way the cylcles in the ecosystem functions. The effects can be a result of the activity that humans elect to engage in, and some of those activities unfortunately impact the cycles of the ecosystem negatively. This is why it is…

Human Impact On Cycles Essay

Human Impact on Cycles We, as humans, have an effect on everyone and everything around us including the four main cycles of the Earth; water cycle, nitrogen cycle, carbon cycle, and the phosphorus cycle. The water cycle is the circulation of the earth's water, in which water evaporates from the surface into the atmosphere, where it condenses and returns back to the Earth’s surface as rain or snow. Water is an essential necessity in every living, biotic thing. Humans have an impact of the water cycle is many different ways…

interactions in the earth’s global skin of air, water, soil, and organisms. I. Sun cycles of matter and gravity sustain life on Earth. 1. The one-way flow of high-quality solar energy through materials and living things (as they eat) produces low-quality energy. Energy can’t be recycled. 2. Matter cycles through parts of the biosphere. 3. Gravity causes the downward movement of chemicals as matter cycles through the earth. J. Solar energy just passes through the earth as electromagnetic…

microorganisms break down some of soil’s organic compounds into simpler inorganic compounds. 6. Matter is recycled through the earth’s ecosystem of air, land, water, and living organisms. This vast global recycling system is composed of nutrient cycles. 7. Scientists study ecosystems through the use of aquarium tanks, greenhouses, and controlled indoor and outdoor chambers. Specific variables are carefully controlled, like temperature, light, carbon dioxide, and humidity. 8. Two principles…

Algal Blooms Naturally in the world, nitrogen and phosphorus is found in lakes and ocean coasts. Algae, a microscopic organism, will feed off of the phosphorus and nitrogen and will multiply really fast (Hoyle, 2005). Commonly known as ‘Red Tides’ (Bruckner, 2012) when seen in large masses in lakes or on coasts, a single celled organism called Pfeisteria…

research into cures for disease. Phosphorus uptake by plants Plants take up phosphorus-containing compounds from the soil through their roots. By adding a small amount of radioactive phosphorus-32 to fertiliser and then measuring the rate at which radioactivity appears in the leaves, it is possible to calculate the rate of uptake of phosphorus from the soil. The information gathered could help plant biologists to identify plant types that can absorb phosphorus quickly. These plants may give better…
